Problems solved by technology

[0006] Analyzing the use of steel bridge asphalt pavement at home and abroad, it is found that poor high temperature stability and fatigue cracking are the main forms of damage to orthotropic steel bridge deck pavement. Insufficient durability, poor durability of bonding between layers, resulting in delamination and slippage of bridge deck and asphalt concrete surface and damage

Embodiment Construction

[0035] The application will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0036] Such as figure 1 As shown, the steel bridge deck pavement structure of the present invention, according to the order from top to bottom, includes an ultra-high viscosity modified asphalt mastic macadam layer 106, an adhesive material 105, a combined connecting layer 104, an ultra-high viscosity The modified asphalt mastic macadam layer and the combined connecting layer are bonded with an adhesive material; The stone layer 103 is formed and directly arranged on the steel plate 101 of the bridge deck.

[0037] 1. Material requirements

[0038] (1) Modified epoxy resin: The polymer resin material produced by the American Dow Chemical Company (DOW) is preferred. Its main component is a binary hybrid polymer resin. The formula does not contain any fillers and volatile solvents. The hybrid polymer system can provide superior low temperature flexibility a...

Abstract

The invention discloses a steel bridge deck paving structure and a construction method thereof. A combined type connecting layer and an ultrahigh-viscosity modified asphalt mastic rubble layer are laid on a bridge deck steel plate of a steel bridge deck in sequence, wherein the combined type connecting layer comprises a first modified epoxy resin and rubble layer and a second modified epoxy resin and rubble layer, a bonding material layer is further arranged between the combined type connecting layer and the ultrahigh-viscosity modified asphalt mastic rubble layer, and the bonding material layer is made of active epoxy resin materials. Compared with a traditional epoxy resin asphalt concrete bridge deck paving layer, the steel bridge deck paving structure and the construction method are low in construction cost, needless for dedicated equipment, beneficial to construction organization and high in construction speed, and have clear advantages on road sections with high traffic pressure.

Description

technical field [0001] The invention belongs to the technical field of steel bridge deck design, construction, maintenance and repair, and in particular relates to a pavement structure of a steel bridge deck and a construction method thereof. Background technique [0002] Steel deck pavement is an important part of the bridge traffic system, and its quality directly affects traffic safety, comfort, bridge durability, investment benefits and social benefits. The emergence of orthotropic bridge deck system has greatly reduced the weight of the bridge, made the span of the bridge longer, and promoted the construction of super-long-span bridges. The steel deck pavement technology is accompanied by the construction of super-long-span bridges. And developed a special paving technology with high technical difficulty. Due to the small rigidity and large deformation of the orthotropic steel bridge deck system, the requirements for the steel deck pavement are very strict, so it has b...
